Outline

The fact that so many different surgical procedures in chronic nasolacrimal duct obstruction are in use, shows that we still do not have for this pathology a reliable surgical technique.

The endonasal dacryocystorhinostomy (endoDCR) is a scar-free surgery, but it has to be underlined that several different surgical procedures can be used: laser, non laser, endoscopic, microscopic, with or without stent.

We perform the endoDCR by an operative microscope, without laser and with a bicanalicular silicone stent implant.

This kind of endoDCR technique seems to be very useful particularly when acute dacryocystitis occurs, both because:

the pus accumulated can be easily drained from the lacrimal sac avoiding the arise of major complications such as orbital cellulitis and the lacrimal sac perforation, and

the impossibility to access to the lacrimal sac via the lacrimal puncta, due to the Rosenmuller valve occlusion.
